Pregnancy outcome after insemination of frozen-thawed bovine semen packaged in two straw sizes: A meta-analysis

Birth of puppies after intrauterine and intratubal insemination with frozen-thawed canine semen

The present study was performed to assess the fertility of frozen-thawed dog semen prepared by freezing with 6% glycerol and thawing at 70 degrees C for 8 sec, and to evaluate the least number of post-thaw spermatozoa necessary to achieve pregnancy by intrauterine or intratubal artificial insemination. It was found that the pregnancy rate of intrauterine artificial insemination was 100% using 6...

Quality of Bovine Chilled or Frozen-Thawed Semen after Addition of Omega-3 Fatty Acids Supplementation to Extender

Successful artificial insemination in the Asian elephant (Elephas maximus) using chilled and frozen-thawed semen

BACKGROUND Artificial insemination (AI) using frozen-thawed semen is well established and routinely used for breeding in various mammalian species. However, there is no report of the birth of elephant calves following AI with frozen-thawed semen. The objective of the present study was to investigate the fertilizing ability of chilled and frozen-thawed semen in the Asian elephant following artif...

Fertility of Ewes after Intrauterine Insemination with Frozen Semen

In an experiment involving the artificial insemination of 312 Merino ewes, fertilization, early (18 day), and late (100 day) pregnancy rates were examined after intrauterine insemination with frozen semen using a laparoscope. Oestrus was synchronized in ewes by progestagen sponge/PMSG treatment. After cervical insemination of fresh semen (control) 55 hrs after sponge removal, the fertilization,...

Distribution of Spermatozoa in the Reproductive Tracts of Sows after Intra-uterine Insemination Using Frozen-thawed Boar Semen

The aims of the present study were to determine the number of spermatozoa in the reproductive tract of sows after intra-uterine insemination (IUI) with frozen-thawed (FT) boar semen and to investigate the influence of adding seminal plasma in the thawing medium on the sperm transport in the female reproductive tract. Fourteen multiparous sows were divided into 3 groups: group I (n= 5), insemina...
